In a nutshell, ramp speed has been changed to just over 12 BPS with first 3 shots semi-auto and only one runaway shot (2 may be tolerated), mandatory handshakes, and tiebreakers will change a bit. There are some other minor changes as well.

Those who use Millennium mode and/or play by those regulations might find this information handy.
